The Pollution Control Department (PCD), announced that PM2.5 microns have reached unhealthy levels. The haze situation in nine northern provinces, the PM2.5 levels were measured between 34 and 128 micrograms […] The PM2.5 level averaged across 18 air quality monitors throughout the Wasatch Front (including Brigham City and Logan) is shown in Figure 8. The average 24-hour PM2.5 concentration consistently exceeded the current 24-hour NAAQS (first enacted in 2006).

It is important to note whether PM2.5 or PM10 data on online websites is represented as AQI or ug/m3. PM2.5 concentration levels were down by 31% from the same time last year, and down 51% from the average of the previous four years. And in Europe, London and Madrid both experienced reductions in These are fine particulate matter (PM2.5) and ground-level ozone (ozone). PM2.5 is smaller than 1/30 the width of one piece of your hair. The particles are so small that they can be breathed deep into the lung and cause serious illness and sometimes death.

Measuring exposure levels of inhalable airborne particles

top level at Torkel Knutssonsgatan) and Uppsala (roof top level at Klostergatan). The. PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM. Air quality monitors measure concentrations of PM throughout the country. On a very clear and non-hazy day, the PM 2.5 concentration can be as low as 5 μg/m 3 or below. The 24-hour concentration of PM 2.5 is considered unhealthy when it rises above 35.4 μg/m 3. Why 24-hour and not a shorter duration when evaluating the health impact of fine particles? The main change is this updated EPA standard, published on December 14th 2012, compared to the previous one (published in 1999), is to reduce (limit) the PM 2.5 AQI level 50 from 15µg/m 3 to 12µg/m 3, and this in order to enforce more strict air quality standards.
